ADJUSTABLE WAINSCOT-MARKER.

Specification of Letters Patent.

Patented May 12, 1914.

Application filed February 18, 1913. Serial No. 749,222.

To all whom it may; concern:

Be it known that I, Isaac A. VILSON, citizen of the United States, residing at Seattle, in the county of King and State of \Vashington, have invented certain new and useful Improvements in Adjustable VVainscot- Markers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in Wainscot markingtools and an object of the invention is to provide such a tool with a removable flexible cutter, which can be adjusted to produce cuts of different sizes.

A further object of the invention is to so form a tool of this class that a guide may be held rigid with respect to the cutter in any adjusted position.

'With these and other objects in view the invention comprises certain constructions, combinations, and arrangements of parts as will be hereinafter more fully described, and claimed.

In the drawings where similar reference characters designate corresponding parts: Figure 1 is a side elevation of the tool forming the subject matter of this invention; Fig. 2 is a vertical longitudinal central sec-- tion through the tool; Fig. 8 is an enlarged vertical transverse section upon the line 33 of Fig. 1; Fig. 1 is a perspective view of the guide member; and 5 and 6 are detail views showing modified forms of cutters usable in the tool.

Generally this invention aims to provide a cutter blade with means for holding the same in any adjusted position, and in further providing a guide which will be held rigid with the cutting blade, the tool so formed being used to decorate plaster walls after the plaster has set sufficiently to be cut neatly by the blade.

Referring to the drawings, the tool is shown as provided with a handle 1, to which are held two flexible telescoping members 2 and 3, a rivet 1, the ends of which are flush with the outside surfaces of the flexible members, being provided for holding said members upon the handle 1. The forward ends 5 and 6 of the flexible members 2 and 3 respectively are each Ushaped, one of said U-shaped ends being smaller than and fitting into the other of said ends. While I have shown this particular means of securing the flexible members 2 and 3 to the handle 1 and this particular method of forming the ends of the flexible members, yet it is to be understood that I may use other means for ac complishing the same result, as it is evident that several means could, be used for accomplishing each result.

Designed to be received by the jaws 5 and 6 is a cutting blade 7 having its point 8 V- shaped, as indicated in Fig. 1 and having parallel sides 9 extending from the point, one of these parallel sides being in engagement with one of the ends of the flexible members 2 and 3. Intel-posed between the parallel sides 9 is a spacing block 10, which block may be made of any suitable material and of any desirable thickness. A guide 11, having a projecting end 12, is provided, the projecting end being held between one of the parallel sides 9 and one of the projecting ends of the flexible members.

In order to draw the two U-shaped ends together, the flexible member 2 carries an internally threaded stud 13, the outer ends of the stud being flared and received by a counter-sunk opening formed in the member 2. A screw 14 having its head flared and engaging a counter-sunk opening in the member 3 is provided, the threads of the screw being designed to engage the internal threads of the stud 13. The shank of the stud 13 is made su'lliciently long to provide for any adjusted opening between the flexible members 2 and 3. By means of the stud and screw just described there is provided simple means for forcing the U-shaped ends 5 and 6 together.

In the use of this tool, the operator will loosen the screw 1-1 until the ends 5 and 6 are separated sufliciently to insert therebetwcen the cutter blade 7 the block 10, and the projecting end 12 of the guide 11, when the screw will then be tightened, the result of which tightening will be to force the ends 5 and 6 together so as to bind all of the elements contained between said ends. The operator then places the lower end (5 upon a suitable straight edge 15, which lies flat against the wall to be decorated, and draws the tool along the straight edge so that the cutting blade will remove a small volume of the plaster, the plaster thus cut passing through the blade and dropping out of the other side. By means of the guide 11, the

upper surface of which is convex, toward the wall, the depth of the cut may be regulated.

Asshown in the Figs. 5 and 6, other forms of cutter blades may be used, the form shown in Fig. 5 being used when" it is desired to produce a bead, and the form shown in Fig; 6 being used when it is desired to produce a square cut. The spacing block lO'may be made of varying thicknesses, as indicated in Figs. 5 and 6, the use of blocks of varying thicknesses being made possible by the flexibility of the members 2 and 3, and the blades 8, 8, and 8".

I claim:

1. In a marking tool, the combination with opposed jaws constituting together a hollow gripping member of cone, form, with an end portion of cylindrical form, the edges overlapping longitudinally, of a block disposed between said jaws, a marker having a portion thereof disposed between one jaw and said block, and means for clamping said jaws and block against said portion of the marker.

2. In a marking tool, the combination with opposed jaws constituting together a I hollow gripping member of cone form, with an end portion of cylindrical form, of a block disposed between said jaws, a marker formed from a strip of metal centrally bent to form spaced parallel arms, said arms, be-

Copies of this patent may be obtained for ing respectively disposed intermediate the jaws and opposite sides of theblock, and means for clampingsaid jaws and block against said arms. r

3. In a'wainscot marking tool, opposed jaws, a marker having parallel sides located within the jaws, one of the sides engaging one of the jaws, a block located between the parallel sides of the marker, a guide part of which lies between the other jaw, and parallel side of the marker, and means for binding the jaws together to hold the guide, marker and block. j

4. In a wainscot marking tool,ithe combi nation with opposed jaws of resilient material substantially semi-circular in cross sec-' tion and movable with reference tov each other without causing their edges to be spaced apart, of a block disposed between said jaws, a marker having parts thereof disposed between the block and said j aws, a guide having a part disposed between one of the jaws and the adjacent part of the marker, and means for clamping said jaws, block and said parts of the marker and guide together. i V

In testimony whereof I aflix my signature in presence of two witnesses.
